There are a lot of big outdoor events going on this weekend, including Saturday's Chargers Fan Fest at the Q, horse racing at Del Mar, and three games at Petco, where the Padres will host the Mets. Fortunately, the weather is going to be great -- if a bit warm. But then, it is August.

Surf: Sea surface temperatures are pleasant, ranging from 66-69 degrees in most areas. But the surf will remain on the small side, says Solspot.com. Forecasters are calling for surf in the 2' to 3' range in most areas. Cautionary note: Lots of stingrays in the nearshore waters. Shuffle your feet.

Thunderstorms: There's a small chance of thunderstorms in the eastern deserts on Saturday and Sunday. But forecasters say the region isn't likely to get the sort of boomers that caused flash flooding on Monday.
